ABSTRACT: Water scarcity is relative and variable concept that can occur at any
level of supply and demand. It is also a social construct, which is linked to
the intervention in the water cycle and changes over time as a result of
natural hydrological change. It is more severe when water acts as a backbone in
economic policies, planning and management methods. Water scarcity can be
expected to increase with most forms of economic development, but, if properly
identified, many of its causes can be expected and avoided or mitigated. However,
the limited irrigation management is considered a very important issue in the
agricultural scope. Therefore, in this study, the
relationship between water, crop production, photosynthesis, crop
transpiration, crop growth, crop yields and water use efficiency have been
discussed under limited irrigation conditions. However, the crops have some
ability to adapt and resist against limited irrigation. Hence, under high
temperate conditions, this is a shortage of water and photosynthesis is
decreased with a pore (stoma) restraining. At the same time, the
evapotranspiration reaches to the utmost value and the water use efficiency rises
because of optimal monitoring of leaf pore (stoma). Therefore, the modality
which is the reduction of the risks and improving industrial control in
incomplete irrigation are the chief constraints of providing irrigation water
in the future, which leads to increased crop production and ultimately
providing a provision of food security.
